12 x 180s Ha (Green)
12 x 180s OIII (Blue)
12 x 180s SII (Red)
Total 108minutes imaged in a single run last night with C9.25" Edge HD and Hyperstar w/ Baader 2" f2 tuned filters.
The shorter exposure times keeps the keyhole structure from blowing out too much. Processed with dark bad pixel mask, but no flats. PixInsight Dynamic Background Extraction, Morphological star reduction, and HDR transform with a star mask to protect the stars. Channels combined in Photoshop.
Looking forward to framing this better and using multiple exposure lengths for the whole nebula, though this framing shows the inner structure ok I think. The collimation was a little off on the Hyperstar so the stars aren't even across the field.
